Abstract
A crane column segment connection system includes first and second column segments with a connector on the second end of the first segment mating with a connector on the first end of the second segment. The connectors each include at least one extension having a through-hole. The through-holes have an axis and are positioned in the extensions such that all through-holes of mating connectors are aligned when the column segments are aligned. In one aspect, the connectors include alignment surfaces cooperating such that when the first and second connectors are being brought together during column assembly, the alignment surfaces guide the column segments in two dimensions within a plane transverse to the axis of the through-holes into a relative position such that the through-holes through the extensions in the connectors are aligned.
